/**
 * Dev-mode error panel (spec: "Dev-mode error panel (HU4)") — the human-
 * facing counterpart to the agent feedback loop; a renderer of live
 * validation output, no new validation logic. Own shadow DOM (style
 * isolation, like widgets), fixed corner, high z-index, non-blocking (never
 * intercepts map interaction outside its own small footprint), folds to a
 * count badge, expands to the full list, click-to-locate flashes the
 * offending element.
